I/O function

Input device
■Outline
Input devices cannot be used for safety sub-function control by network. Input devices for functional safety have the following
characteristics.
• Input device selection
A device can be freely assigned to the input signal of the CN8-4/CN8-5 pin by parameter.
• Duplication of the input wiring
Input errors can be detected immediately by verifying the input signal with duplicated wiring.
• Diagnosis with test pulses
Failure diagnosis including external wiring can be performed by sending pulse signals that are temporarily turned off when the
input signals are on.
• Noise elimination filter
This is a function that can reduce noise for input signals.
■Input device selection
• Input device selection
Select the input device to be assigned to the input signal of the CN8-4/CN8-5 pin with [Pr. PSD02 Input device selection DI1].
CN8 pin No.

For details on each input device, refer to the following items. For multi-axis servo amplifiers, axes to use input signals can be
selected from any of the following: One input signal activates the safety sub-function for the A-axis only, or activates the safety
sub-function for the A, B, and C-axes at the same time.
Input signal
STOC (STO command)
SS1C (SS1 command)
SS2C (SS2 command)
SLS1C (SLS1 command)
SLS2C (SLS2 command)
SLS3C (SLS3 command)
SLS4C (SLS4 command)
SDIPC (SDIP command)
SDINC (SDIN command)
SLIC (SLI command)
SLT1C (SLT1 command)
SLT2C (SLT2 command)
SLT3C (SLT3 command)
SLT4C (SLT4 command)
• Input device automatic activation selection
Setting [Pr. PSD01 Input device automatic activation selection] activates the operation command of each function
automatically.
The automatically activated input device will be enabled regardless of the input device condition, and the corresponding
function will operate automatically.
For the input devices that can be automatically activated, refer to [Pr. PSD01 Input device automatic activation selection].
